| abstract | 【Task】 Improvement of start-up method (step of increasing acrolein supply amount (load amount) from reaction stopped state to predetermined reaction condition) when producing acrylic acid by catalytic vapor phase oxidation of acrolein under high load condition is provided The [Solution] In this method, at the start-up of the reaction, the acrolein conversion is 90 mol% or more, the maximum peak temperature of the catalyst layer in each reaction zone is 400 ° C. or less, and ΔT (catalyst layer) in the catalyst layer in each reaction zone While adjusting at least one of the reaction temperature, the reaction raw material gas composition, and the reaction raw material gas flow rate so that the sum of the maximum peak temperature and the reaction temperature is maintained at 150 ° C. or lower, respectively, a predetermined reaction raw material gas composition and It is characterized by increasing the supply amount of acrolein until the reaction raw material gas flow rate is reached. According to this method, the reaction quickly reaches a steady state, and a high acrylic acid yield is stably achieved from the beginning of the reaction. [Selection figure] None |
